Default AMS tuning... advice????

I have an appointment at Automotosports (AMS) August 10th for a full tune.

1). Is there anything they should know that is Miata/Megasquirt specific before I go? They specialize in EVOs but they say they can work with a Megasquirt easily. I don't want to spend hundreds extra if I can simply supply them with some preliminary info.

2). Can someone please print screen their "engine constants" window with 460cc inj on a 1.8l?

just wanna make sure everything goes as smooth as possible on the 10th... THANKS!!

While AMS specializes in EVOs, they work on all makes, and are building a Nissan GTR practice as well. They have done several Miata's with MS before (including mine) and have created a small database of MSQ files for Miatas. Chris (tuner) is reasonably well versed in MS. However, you don't want to pay him to go through each screen and type in values!

Make sure you have upgraded the firmware to what you need. I assume you have replaced the MAF with an IAT, so make sure the firmware is updated for that.

I can send you my engine constants (or entire MSQ if you want) when I get home tonight if you want ( 420 CC injectors, MS PNP 9495, 1.8, T2554 turbo, '99 head). Not sure if this is close enough to your set up to be of help......

How much HP are you expecting?

I got my car tuned there by Chris, he only charged me $1200 for two tunes, one gas, one race gas, $900 for one map tune. I know last time I was in there shop they said they bought a Miata with a Megasquirt.

i have been running on my own street tune for a while now at 6psi so all of my values are functioning properly.

the engine constants are easy to calc out but i wanted to double check to see if i made any major errors... before i sent my 460s to deatschwerks my engine would just flood with key on and my coils were fried (brain typed in a wrong value in the MS i got from him grrr lol) but that problem was resolved.

i am expecting anywhere between 230-250hp at 12psi from my 2560R... ill be happy if its even 229.99 hp as long as its a safe daily tune u know?

lol @ $900 for 3-hours of work at the most, if the tuner is retarded and blind. I tuned my car after reading and asking questions, the first time I've ever attempted to tune a car on a dyno, and was done in 90-minutes. If you're taking a car in there which doesn't run with no work at all on fuel tables or enrichments then I'd probably charge you $900 too.

As for the "race fuel" tune, the tuner is literally going to add 3-6* of spark in the detonation limited cells and see if there's an increase in output from your base tune...so an additional $300 for ~3-pulls with more spark angle sounds a little expensive to me too.

What does AMS call a "map tune"?

I know AMS is increadibly ganxter, but that's way too expensive.

Chris Black is one of the most respected tuners in the business, it cost that much because of who he is most likely. 900 is steep, but it includes all the time it takes him to tune it, also, knowing your motor is in good hands.

My car was tuned by the most respected e-thug on the planet and it was $100 and I promise you his car won't be any faster than any turbo car I or Savington tuned. I respect the craft and understand that I'm a novice...but $1200 is the MoTec/Patek/M&M price. MS is a 1-hour job.

Why is he so respectable? I'm asking a genuine question...why is he so well respected? I don't know the guy.

In for results and final cost on this one. I'm curious to see how good these tunes are.

How much power can be squeezed out of each particular setup at a certain amount of boost. Reliability as well but we might have to wait on that one.

Not because I want to bring my car there, I'm just curious.

For now, I'm sticking with the butt dyno and when I get some, the patented hustler det can method so I can get it close and not spend a **** ton of money.

I think Chris's resume speaks for its self:

Tuned the following to name a few:
2009 Redline Time Attack Unlimited AWD championship car
2008 Sport Compact Car Ultimate Street Car Challenge Winner
World's Highest horsepower Evo 1181 AWHP
4 seasons on the Original Ams 2.3 Stroker Engine!
2009 CMRC Champion
Tuned Winner of the 'Top Car Challange by Castrol, made 1035 hp on non-leaded pump
As well as over 1000 other cars

EDIT: Went on their website and it now says $235 hr for tuning, rather than a flat rate. Also, I like them because they're factory trained and certified in the AEM EMS.

That's the only one that matters. Hopefully he compensates for the stretchy timing-belt and shitty 2-tooth wheel.

Those are some impressive accolades but at the same time HKSturboMiata is having an issue with the motor they built with 1500 miles on it so the verdict isn't in yet.

Just saying.

easy fellas! the only reason why im willing to pay so much for a tune is that this car is my DD and i am still learning MS / tunerstudio... my next turbo project will be 100% DIY. besides, i heard many many many good things about chris at AMS.

new spark plugs in... check
tools in trunk Justin Case... check
extra zip ties... check
japanese friend to fit hands in tight places... check
football to kill time with said friend... check

WISH ME (or my motor) LUCK!!!
